No, not at all. The sample I used serves to illustrate the overarching point which is that the 54% average is made up of those who hit 100% (Rodgers) and those who hit 0% (Newton). Thus, to make a blanket statement that only 54% of 300+ YPG performances lead to victories is misleading.
I'd be interested in what the league-wide loss margin is for QBs who throw for 300 yards and still lose. I just flipped through Rodgers' game logs and in the 7 or 8 games he threw for 300 and they lost, it was a TD once and then the rest were all 1-3 points. Looking at Netwon, they lost by 7 or less each time too. I decided to look at Rivers too, since he is another 300 yard bomber and out of the roughly 10 games the Chargers have lost when he threw 300 yards they were all under 7 points too except for one game against the Patriots where they lost by 14. BTW, for laughs I looked at Alex Smith, and in the two games he hit 300 they lost, but by a FG each time.
A loss is a loss, but I guess it is better to at least be in the game instead of getting blown out by 21+ points because your QB struggles to throw it for 150 yards. The loss is always a punch in the gut, but at least you feel better about your team's chances next week after a close loss instead of wondering if they'll ever win again after getting blown out 0-41 with a QB who just threw for 70 yards.
